Four screws on the dash surround (thing with the buttons/switchblocks on it for lights etc) take that off and unplug the look from the switchblocks. The screws are located just above where the clucter is throught the steerign wheel and two more either side of it under the dash.
Then there is only 2 screws either side of the cluster on white tabs you need to undo then pull it out.
Make sure your new cluster is out of a VN/VP
